As of today, the PlayStation Portable Core Pack (which includes just the battery and power cord) drops 30 bucks to $170. With that savings you could buy a bargain-priced game or a memory stick to go with it (you did want to save that game, didn't you?). Now things start to get interesting - anybody been waiting for this? It's still not head to head with the DS, but there is the bigger screen and video playback capability...
